PURPOSE:To reduce number of delay lines and to decrease the circuit scale by constituting a transversal filter constituting an automatic equalizer with a cyclic filter. CONSTITUTION:Two delay lines 11-1, 11-2 are used and the input and output of them are fed to an adder 13 via weighting devices 12-0-12-2. Further, the input and output of the delay line 11-2 are fed to an adder 23 via weighting devices 22-2, 22-2, an output of an adder 23 is fed back to the adder 21 and fed back negatively to the input signal. Then a signal in which transmission waveform distortion of the input signal on a time axis from the adder 13 is compensated is outputted. |
